context: floor adjustlinkrev graph walk during copy tracing

The `_adjustlinkrev` method gains an optional "stoprev" argument. The linkrev
adjustment will give up once this floor is reached. The relevant functions
using `_adjustlinkrev` are updated to pass an appropriate value in the copy
tracing code.

In some private repository, about 10% of the status call triggered the
pathological case addressed by this change. The speedup varies from one call
to another, the best-observed win is moving from 170s to 11s.

The effect of this change can be seen in the public pypy repository, running the
following command:

    hg perftracecopies --source 83c9ff0c0206 --destination 59c79103d5b0
